I think this might be linked to cf_lock.tcdb file size:
<a class="moz-txt-link-freetext" href="https://www.rudder-project.org/redmine/issues/4769">https://www.rudder-project.org/redmine/issues/4769</a><br>
<br>
This file grow bigger and bigger with time, impacting the
performance of cf-agent.<br>
<br>
When your tmpfs got full, cf-agent cannot run anymore.<br>
<br>
This bug has less impact on CFEngine 3.4, so we only fixed it in 2.9
(using CFEngine 3.5).<br>
<br>
To resolve your problem, you can wipe that file regularly using a
Cron ( /etc/cron.d/clean-rudder-locks)<br>
<br>
<pre>*/5 * * * * root if [ `ls -l /var/rudder/cfengine-community/state/cf_lock.tcdb | cut -f 5 -d " "` -gt "10485760" ]; then rm -rf /var/rudder/cfengine-community/state/cf_lock.tcdb*; fi</pre>
<br>
I suggest to share that to your nodes using a 'copy from shared
folder' Directive, (or a 'cron management' / 'Job Scheduler' ).<br>
<br>
Next releases (2.9.5 and 2.10.1, will contain the fix)<br>
